We've all heard the argument of the do-it-yourselfer. Doing the job on your own can bring a sense of satisfaction and save money. When things don't go right the results may not be so warming or economical. Thirteen beers or three fried alternators into a pile of sheared bolts and bruised knuckles can result in a job…

Back in the days of carbureted and plentiful used Plymouth Satellites, B-52's frontman Fred sang of the devil in his car. Beehive sporting singer Kate did Fred one better by wailing that she had the devil in her CAR-buretor! Having Beelzebub in the float bowl and demons clogging the jets is not a good thing at all. A…

Along with swapping out the air filter and changing the oil, replacing the spark plugs is one of the few things left that require service on a modern gasoline engine. Some newer than the twenty-year old junk classics in our garage have negated even this task with spark plugs made of space-age materials that can live…

With the weekend nearly here, it's time to pop open the hood and take a trip down the trail of parts. Those battery terminals and posts that look like a high school science experiment gone wrong need to be cleaned. As long as you're there, find the right dipstick and check the oil. If it looks as if it could be…

The automobile contains a number of fluids that should all stay where they're supposed to be. Oil spots, coolant leaks, mystery drips, and other tell tale signs of fluids leaving their rightful place in the automobile are a sign to take heed of maintenance. Denying the existence of the ever-growing number of oil spots…

In our explorations into parts and parts replacement, we often mention the service manual. While there are certainly a large part of the monkeywrenching public who would throw directions to the wind, instructions can be a good thing when it comes to things like working brakes and wheels not falling off the car.…

While there is a difference between brake pads and shoes, the desired result is always the same when the foot goes down on the brake pedal. Brake pads clamp down onto a rotating disc. Brake shoes push out Flintstones-style onto a rotating drum. Inertia gets turned into heat via the miracle of friction. If all goes…

Today's question comes to us courtesy of a reader we'll just call Gregor. True, there are some green zip ties lashing down the front of our WRX. Though, the plastic bolts they replaced were actually inferior. So we can't count that. We do remember a friend with a mid-80s Thunderbird that carried 5 gallons of…

The fluid that exists as brake fluid is in reality hydraulic fluid. The helpful property of brake fluid is that it cannot be compressed. This comes in handy when the brake pedal is pushed down. Brake fluid links the parts of the brake system together as one. Brake pedal goes down. Friction is achieved! A hydraulic…

Mechanical know how in our case has come largely from two sources. There have been those kind enough to show the way, and there has been the hard way. A long and proud lineup of 500-dollar cars has steered us mostly down the latter route. The way we learned about how and why to run a compression check on an engine…

For a long number of years even the idea of washing and waxing our car was unnecessary. Cleanup meant maybe a hosing off, and adding another layer of rattle can primer to key spots. The first paint job worthy of a wash and wax was a defining moment. Washing and waxing the new paint on the old car was suddenly an…

Whichever crackpot invented the wheel had no idea what it would lead to. Land speed records. Plus one measures of gravity on a skidpad. Four-second quarter miles. 30-inch spinners! Multiple volumes of unmentionable bad craziness. And dirt crusted wheels. While filthy wheels may not be of great concern for ox-drawn…

Some of us may already be hurtling down the roads of America in an Ultra Van or Hoonabago in celebration of Memorial Day. More still may have decided to avoid the crowds and stay put. If you haven't left yet, then check the tire pressure before loading up the Town & Country wagon with 500 pounds of cargo. Make sure…

With gasoline prices obviously not trending downward, cash-strapped drivers are finding themselves flummoxed as to how get the best bang for their increasingly thin buck. Read on to take the first step onto the path of improved fuel efficiency.

Automobile wheels spin round thanks to the miracle of wheel bearings. The bearings themselves contain rollers that spin around inside a cage. Wheel bearings are often tapered against the coned races in which they spin in order to handle the lateral forces placed against the wheels when the vehicle turns. Given the…

The history behind the modern strut type suspension has its origins in the United Kingdom. Henny Youngman would find a joke here. Something about Scotsmen, a Lotus, a spring, and a shock absorber. The punchline would be the MacPherson strut suspension. I love this crowd! The integral spring and shock absorber…

Without the shock absorber the modern automobile would simply flail about on its springs. The shock absorber is technically a damper. The shock absorber works to dampen the bounce created by bumps in the road and the weight of the vehicle acting on the suspension and springs. The less obvious yet more important…

As we're off to Las Vegas for Mopars at the Strip this weekend and riding the red-eye out to the New York Auto Show next week, the Trail of Parts will remain apart until our return. In the meantime we would like to call upon our readers to suggest both useful and amusing topics for this ongoing exploration into the…
